Description
Technical field
The invention belongs to road prevention device field, especially relevant with a kind of road prevention device.
Background technology
It is different that the most conventional highway guard rail presses energy-absorbing mode, flexible safety fence can be divided into, semi-rigidity rail and stiff safety fence three major types, Cable Barrier, corrugated beam barrier and concrete guardrail are the canonic forms of this three class, it is fewer and feweri that Cable Barrier uses on highway, crashworthiness is poor, corrugated beam barrier has certain rigidity and toughness, by utilizing soil matrix, column, the deformation of crossbeam absorbs collision energy, and force errant vehicle to change direction, but current semirigid corrugated beam barrier does not the most possess enough intensity to resist the collision of vehicle, collision energy is beyond the maximum absorbance capacity of corrugated beam barrier, interception car failure or waveform section crossbeam is easily occurred to insert in car；Meanwhile, at night-time hours, corrugated beam barrier is difficult to be identified, and does not possess good visually oriented property；Concrete guardrail is a kind of cement concrete wall type structure with certain section configuration, collision process relies on vehicle front climb or turn to and absorb collision energy, the cross sectional shape of concrete guardrail and physical dimension directly affect collision action effect, and above-mentioned several highway guard rails are typically all fixedly mounted in the middle of road or both sides, make function path single, maintenance inconvenience.
Summary of the invention
The purpose of the present invention is intended to overcome existing road guard rail to there is drawbacks described above, it is provided that a kind of anti-collision effect is good, can play guide effect, the road prevention device of easy maintenance and installation.
nullFor this，The present invention is by the following technical solutions: road prevention device，It is characterized in that，Described road prevention device includes the Shi Neng bindiny mechanism described in several anti-collision units and each two between anti-collision unit，Each anti-collision unit includes Guard fence base、Roll guidance set and support installing mechanism，The sidepiece of Guard fence base is provided with installation cavity，Roll guidance set and include rolling member and roller bearing，Roller bearing is vertically installed in the installation cavity of described Guard fence base，Rolling member is set in this roller bearing，Make rolling member can rotate centered by roller bearing and the partial outer face of rolling member is towards road-center，Described support installing mechanism includes fixed cover pier and swinging axle，Fixed cover pier is fixed on subsurface by cement casting，The end face making fixed cover pier is equal with ground，Fixed cover pier top face is provided with axial counterbore，The middle part of described Guard fence base is provided with up/down perforation and the installing hole corresponding with described axial counterbore，Described swinging axle makes to be plugged in bottom it in described axial counterbore through described installing hole，Make the Guard fence base can rotation centered by described swinging axle，A soft sleeve it is set with on the periphery of described swinging axle，Cushioning effect can be played；Described Shi Neng bindiny mechanism include connecting assembly and being arranged at connect on assembly release can assembly, the two ends connecting assembly connect one end that described two adjacent Guard fence bases are adjacent respectively, when Guard fence base is by vehicular impact power, more weak owing to connecting the firmness of the relative anti-collision unit of degree of being connected firmly at assembly, therefore connect assembly and fracture or damaged first occurs under the effect of impulsive force, but release can under the effect of assembly can effective slow release impulsive force, reduce the loss of vehicle.
